Hi all
just become a member of the site, if poss can someone shed some light on issues i have with outboard
just brought a second hand meriner 20hp two stroke i beleave its around 1985, this is whats on the stamp MARINER 20ML, 6A9, L , 308183.
having problems starting it, it takes quite some pulls and have to pull the throttle to assit with the starting, once running it seems to be okay if the tick over is adjusted to tick a bit faster. carried out a compession test once it had been running for a while and got almost 100psi from both piston, it smokes alot, i have been mixing 50/1. i did listern for any noises when it was running, no rumbles but a small rattling from the top ( fly wheel area ) once reved it goes away. the guy said it hadnt been serviced for a year and it needed one, it does pump water okay.
any help would be appriciated

thanks Matt
